摘　　要：采用溶液转相乳液聚合方法制备阳离子丙烯酸树脂/醇酸树脂乳液(WPAAR),探讨了丙烯酸十八酯(SA)的用量对阳离子丙烯酸树脂/醇酸树脂乳液性能的影响,并通过AFM、TGA、流变仪及动态光散射仪等对乳液性能进行表征,结果表明:当w(SA)=1.54%时,涂膜的吸水率为2%,硬度可达H,抗冲击性达到50cm,热失重5%时的分解温度为219.69℃,同时随SA含量的增加,涂膜表面粗糙度降低,乳液粒径先减小后增大,乳液稳定性提高,乳液具有良好的触变性.The preparation of cationic acrylic resin/alkyd resin emulsion （WPAAR） by solution phase emulsion polymerization was performed. The effects of different amounts of stearyl acrylate（SA）on the properties of WPAAR were studied. The properties of emulsion were characterized by AFM, TGA, rheometer and dynamic light scattering instrument. The results showed that when ω（SA）=1.54% ,the water absorption was 2% ,hardness up to H,and Impact resistance reached 50 cm. The thermal decomposition temperature of 5 % weight loss is 219. 69℃. With increasing the SA value,The surface roughness of the film is reduced,The emulsion particle size decreases first and then increases, the emulsion stability is improved,and the emulsion has good thixotropy.
